Public bug reported:

If I have a 10 second clip that I've trimmed down to 4 seconds (say 2 seconds from the front, and 4 seconds from the back), then duplicate it and reverse it, the reversed clip plays the wrong section.
Essentially, it reverses the clip, but not the "window" into the clip.

To "fix" this, we need to reverse the trim. So our trimmed reversed clip
needs 4 seconds trimmed from the front and 2 seconds from the back.

This makes sense once you understand it, but most people wouldn't
realise that after trimming a clip to exactly what they want, why
reversing it doesn't work. The reverse effect would often be used in the
middle of a clip, i.e. you have a clip of a dog running, you cut out a
short funny section, duplicate it so you have 3 copys of it, and reverse
the middle one, so that the dog now appears to run along, do the funny
thing, do the funny thing in reverse, do the funny thing again and
continue with the rest of the main clip, all seamlessly.

Ubuntu 10.10
